Abstract

This article probes the usefulness of selected theories from Cognitive Linguistics in the context of statutory interpretation. The presumption of legal language is a well-established rule of statutory construction in Polish legal practice that comes from the internationally recognised theory by Jerzy Wróblewski. It rests on a controversial assumption that there are different levels of generality in legal language (i.e. the language of statutes) and a single term may be given different meanings depending on the level of generality that is referred to. The authors use the notion of basic level categorisation from the cognitive theory of prototypes to explain this mechanism. Legal concepts, not unlike ordinary concepts, form hierarchical taxonomies. A single term may denote concepts that are situated at different levels in different conceptual taxonomies. In the absence of special circumstances, a legal term should be given the meaning that resides at a higher level of categorisation in the respective legal taxonomy. This way, the presumption of legal language is found to be justified on both linguistic and psychological grounds.
